Scratch 2.0 でプログラミングコンテストに参加する方法

1. Create a Scratch 2.0 project which solves the problem.

   • Use when [Flag] clicked block to specify the entry point.

   • Use ask ... and wait block to get a value from standard input. (The value will be stored in answer.) (The asking message is arbitrary. )

   • Use say ... block to output a line to standard output. (Use think ... block to output a line to stderr.)

   • Use stop ... block to terminate your program in the middle of the script. (The option is arbitrary. )

2. Save your project as a .sb2 file.

3. python sb2_to_cpp.py scratch_project_file.sb2 -o output_file.cpp

4. submit the content of output_file.cpp.
